A strange meeting

Today I had a strange meeting with a person whom I had not known before. The first time that one meets a person on skype it is very difficult because one doesn´t know who this person is. Also if the person speaks a different language than one (correcto pero no entiendo el sentido) . The good news for me is that I can understand better English than the last year, but it is very difficult for me speak fluently or without a strong accent.

Thank you for correcting me

puedes decir: thanks for correcting me or thank you for correcting me (NO: thanks you for correcting me)

we talk on skype, we meet on skype, we argue on skype.  Usas ON (claro, entiendo "through")

whom- objeto directo o indirecto.  who-sujeto. Aqui, es "whom" porque es objeto directo del verbo "known".Pero no te preocupas porque ingleshablantes no hablan correctamente tampoco. Pero, cuando se escribe, intenta usarlo correctamente, parece que eres muy inteligente.
